7. ln a printing telegraph, vthe combine tion of a main line, receiving relays therein responsive to current impulses in the main line, a laterally moving paper carrier, means for moving the paper across the t'ace of said carrier, anelectromagnet rior op- @ratingsaid means, an energizing circuit for said electromagnet having two break points in series therein, one im the path VVor' the paper carrier and closed therebyvvhen the paper carrier reaches its initial position, the other controlled by a receiving relay and closed upon the 'energization thereof in response to an impulse from a distant station. 8. ln a printing telegraph, the combination of a laterally moving paper carriage, a

reset magnet therefor whereby the" paper v carriage may be returned to initial position from any 'poin't in its travel, an energizing circuit therefor, a paper lift magnet, and an 'energizing circuit therefor having two break points in series therein closed by the paper carriage when it reaches its initial position and by the armature of the reset.- magnet respecti-icly \vhereby,.the paper is moved across the -face otthe'carriage.

9. In a printing machineg'/ the combination v of a laterally moving paper carriage, an electromagnet, a circuit including said electrcmagnet closed by said carriage, an armature for said electromagnet, a spring-pressed plunger carried thereby, a pivoted member in the path of said plunger and against which the plunger contacts thereby gripping the paper, a bell crank lever molihted on the armature, and a mechanical connection between said plunger and said lever whereby the outer end of the plunger ia moved forward and upward
